Hey guys, just wondering if anyone can give me a report on their carbine gamo. I'm thinking off sending one to my dad for helping with his english sparrow and starling population. The Cros. G-1 i sent him is perfect for his squirrels but is to powerful and loud(he says) for everyday shooting at the pest birds. He has neighbors and wants to keep things on the lowdown. I found a carbine sport at a great price, leftover stock, and saw it was in the R-7 range of power. 700ish feet a sec in .177. I was wondering if the trigger is upgradable, if it is quieter than the average gamo(it has a steel barrel rather that the sleeved plastic kind) and if it would be a good gun for the task at hand? Also is it upgradable to the nitro ram? Thanks for any info .. J
